Description
[technical field]
This utility model relates to a kind of simple unilateral bolt fastener, belongs to civil construction project, mechanical assembly technique neck
Territory.
[background technology]
For the plain bolt being made up of screw rod and nut commonly used at present, when carrying out terminal operation, need to be
Screw rod binding nut are inserted in side, are then tightened by nut at opposite side instrument, and installation requirement installation personnel is simultaneously at structure
The operation of part both sides.But relative to the installation of opening section component more typically, for such as closed cross-section member and inconvenience
For touching the component of wherein one side, this bolt commonly used is using and inconvenient.As concrete filled steel tube,
Beam-column connection etc., owing to column section mostly is closed section, plain bolt can not operate on both sides, therefore common side
Method cannot be installed.The common one-way bolt that expands is because being difficult to the applying of bolt pretightening, and fastening effect is also unable to reach bigger
Requirement is designed under load.And the reserved required precision of punching bolt-for-bolt hole of the prior art is the highest, in-site installation
Difficulty is big, and is difficult to apply at side column and corner post node.And in existing monolateral bolt, it is not suitable for large span or big load
Structure, and need more complicated installation tool and cumbersome installation steps.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of simple unilateral bolt fastener,
It is capable of monolateral enforcement terminal operation, and easy to use, improve the fastening effect of bolt.
For achieving the above object, the utility model proposes a kind of simple unilateral bolt fastener, including snap bolt, ring
Set, some elastomers, some baffle elements and fixed cover, the body of rod of described snap bolt is arranged with threaded ring set, institute
Stating and be evenly distributed with elastomer on the periphery of ring set, described elastomer is provided with baffle element, described baffle element and elastomer
Connection end is arcuate shape, and the body of rod of described snap bolt is arranged with the fixed cover compressing baffle element, described fixed cover and circle
The body of rod of hook bolt is threaded, and the front end of described fixed cover is provided with connector, described connector is arranged with and turns set.
As preferably, the diameter of described fixed cover and the equal diameters of installing hole.
As preferably, the cross section of described connector is regular polygon shape.
As preferably, the front end of the body of rod of described snap bolt is provided with square toes.
The beneficial effects of the utility model: this utility model in use, by fixed cover and ring set rotation set at snap bolt
The body of rod on, turn ring set until conflicting with the round end of snap bolt, and ensure to leave between fixed cover and ring set certain
Interval is available for baffle element change in location, the snap bolt being cased with ring set and fixed cover is being inserted installing hole, until baffle element is complete
Complete through the rear end of installing hole, now, elastomer recovers normal condition and is supported baffle element, then by turning set drive
Fixed cover rotates, until baffle element is compressed by fixed cover, takes away and turns set, then rotation set fixes nut on the body of rod of snap bolt
And tighten, during insertion, due to the deformation of elastomer so that baffle element generation change in location, it is impossible to stop, with prior art
Compare, it is possible to realize monolateral enforcement terminal operation, and easy to use, improve the fastening effect of bolt.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of simple unilateral bolt fastener of this utility model；
Fig. 2 is the scheme of installation of a kind of simple unilateral bolt fastener of this utility model.
In figure: 1-snap bolt, 2-ring set, 3-elastomer, 4-baffle element, 5-fixed cover, 6-connector, 7-turn set,
8-installing hole, 9-square toes, 10-fix nut.
[detailed description of the invention]
Refering to Fig. 1,2, a kind of simple unilateral bolt fastener of this utility model, including snap bolt 1, ring set 2, some bullets
Gonosome 3, some baffle elements 4 and fixed cover 5, the body of rod of described snap bolt 1 is arranged with threaded ring set 2, described ring
Being evenly distributed with elastomer 3 on the periphery of set 2, described elastomer 3 is provided with baffle element 4, described baffle element 4 and elastomer 3
Connection end be arcuate shape, the body of rod of described snap bolt 1 is arranged with compress baffle element 4 fixed cover 5, described fixed cover
5 threaded with the body of rod of snap bolt 1, and the front end of described fixed cover 5 is provided with connector 6, described connector 6 is arranged with stubborn
Dynamic set 7, the diameter of described fixed cover 5 and the equal diameters of installing hole 8, the cross section of described connector 6 is regular polygon shape,
The front end of the body of rod of described snap bolt 1 is provided with square toes 9.
Utility model works process:
Fixed cover 5 and ring set 2 rotation set in the course of the work, are being justified by a kind of simple unilateral bolt fastener of this utility model
On the body of rod of hook bolt 1, turn ring set 2 and conflict until the round end with snap bolt 1, and ensure between fixed cover 5 and ring set 2
Leave certain interval and be available for baffle element 4 change in location, the snap bolt 1 being cased with ring set 2 and fixed cover 5 is being inserted installing hole
8, until baffle element 4 passes fully through the rear end of installing hole 8, now, elastomer 3 recovers normal condition and is supported baffle element 4,
Then pass through to turn set 7 drive fixed covers 5 to rotate, until baffle element 4 is compressed by fixed cover 5, take away and turn set 7, then at round end
On the body of rod of bolt 1, rotation set is fixed nut 10 and tightens, during insertion, due to the deformation of elastomer 3 so that baffle element 4 occurs position
Put change, it is impossible to stop, compared with prior art, it is possible to realize monolateral enforcement terminal operation, and easy to use, improve
The fastening effect of bolt.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
